All of the above factors should be carefully considered when choosing a marine battery charger for your needs. 1  Input voltage for marine batteries is usually 120 or 230 VAC. 2  Battery type is typically either gel, flooded, or AGM. 3  Battery capacity is listed on the battery as Ah.
Watts = volts x amps a 12volt battery needs an incoming current of at least 13 volts to charge it; 13.5 volts is better. so if the output VOLTAGE of the panel is less than 13 volts it wont do anything.Even if it is, 10 / 13.5 = .74 amp.(three quarters). deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah-would be maybe two days of full sunlight-with only a 50% charge, or about 12.2 Volts.
